In the tech sector, scams are not uncommon, and the electronics industry is no exception. One common scam involves changing the markings on chips to make them appear more valuable. The author had a personal experience with this when restoring an Acorn Atom. They purchased a Rockwell R65C02 chip, which was supposed to be a […]

Summary: This book on Data Engineering Design Patterns is a unique project that will be released gradually, with the author incorporating feedback from readers to create a comprehensive and innovative guide. The author’s motivation comes from their passion for writing and the challenge of condensing their 20+ years of data engineering experience into a book. […]
The C++ library has traditionally relied on stream classes for reading and parsing strings, but streams can be surprisingly slow. Some Node.js engineers, however, prefer stream classes for string building due to perceived performance benefits. To test this, an experiment was conducted replacing the ‘%’ character in strings with ‘%25’ using both traditional string construction […]
In the early 1920s, scientists Otto Stern and Walther Gerlach conducted an experiment involving silver atoms and a magnetic field. They were aiming to disprove quantum theory, but instead, they made a significant discovery. The silver atoms, when subjected to the magnetic field, split into two distinct paths. This finding confirmed the existence of quantum […]
Researchers at the University of Cambridge have used diamond quantum sensing to study the surface of hematite, a type of iron oxide. They observed magnetic monopoles, or isolated magnetic charges, gliding across the swirling textures of the hematite. This is the first time that naturally occurring emergent monopoles have been experimentally observed. The research also […]
The Wikimedia Foundation has announced the launch of Wikifunctions, its first new project in over a decade. Wikifunctions will create a library of functions that can be used to answer questions and enhance knowledge on Wikimedia projects and beyond. These functions, which are sequences of programming instructions that make calculations, can exist in any language, […]
The Binarly research team has discovered a set of security vulnerabilities called LogoFAIL that affect image parsing libraries used in system firmware during the device boot process. These vulnerabilities impact major device manufacturers on both x86 and ARM-based devices, rendering security measures like Secure Boot ineffective. The vulnerabilities allow attackers to store malicious logo images […]
In this blog article, we delve into the controversial debate surrounding whether accelerated backhopping (ABH) can provide a competitive advantage in the 100m dash. ABH is a bug in the Source engine movement code that allows players to move faster than intended. The code for ABH involves various calculations to determine the player’s speed boost. […]
Sound ID is a new feature in the Merlin Bird ID app that allows users to listen to the birds around them and see live predictions of which species are singing. The app currently identifies 458 bird species in the U.S. and Canada based on their sounds, with more species and regions to come. Sound […]
The ESP32 is a popular microcontroller known for its low price and useful features such as dual-core CPU, Wi-Fi, and Bluetooth connectivity. However, the wireless functionality of the ESP32 is distributed as precompiled closed-source libraries, which can limit customization and security auditing. In an effort to create an open-source alternative, the author aims to reverse […]
